In the SK4.10 / SK5.12 systems, a maximum of 2 GB is available as internal PTO ring memory. Each data record of a stroke is stored in the PTO ring memory. The data can be read out via network or USB stick. With the PTO ring memory, the oldest data is deleted when the 2 GB limit is reached.

There are 2 ways to perform a software update on an SK4.10 / SK5.12:

1. USB:
The monitoring system can be updated with the help of a USB stick. Instructions for this are available as a PDF

2. Network:
With the help of the SK-RemoteController, an update can be imported via the network. This update should only be performed by an SK technician.

Any USB stick with FAT32 or exFAT formatting can be used.
However, the following USB sticks are recommended for the best performance on the systems:
